Architecture
That Breathes

As a Software Architecture Lead, I design systems that teams actually want to use. Not architecture that looks impressive in diagrams but falls apart under load, but the kind that makes the right patterns obvious and guides developers toward maintainable solutions.

I focus on building frameworks that scale, making complexity manageable, and ensuring systems still make sense six months later. Before Moxie, I led teams through legacy system redesigns, drastically cut infrastructure costs through better architecture, rewrote critical services for performance, and built real-time collaborative systems at scale.

Good architecture is mostly invisible, it works so well that people forget it exists. That's the goal: systems that feel inevitable because they align with how people actually work.
